To aZZ whom, it may concern.-

useful Improvements in Dish-Washing Ma-' chines; andI do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the" art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this 4 specification.

Figure l of the drawings is a representation of a central vertical section of the invention. Fig. 2 is a plan view of the invention. Fig. 3 is a fragmentary section showing modification of strainer. Fig. 4 is a plan view of tubes with'radiating discharging-arms. Fig. 5 is a detail of bearing for spiral piston-rod. Fig. 6. is a detail of plain piston rod.

The object of this invention is to provide a practical and efficient device for washing dishes, and by means of which they can be readily, rapidly and thoroughly cleaned,.and

it consists in the novel construction and combination of parts, all as hereinafter described v ever considered to be essential to a successful and pointed out in the appended claims.

Referring to the accompanying drawings,

the letter A' designates a receptacle, which may be made of tin or other suitable material, and of different shapes and dimensions. Supported in said receptacle a short distance above the bottom thereof, is a perforated false bottom B, which is designed toform a sup-' port for the dishes during the operation of washing, as hereinafter more fully described.

- Upon one side of said receptacle is formed an external spout or tube 0, which may, as shown,

extend the full height of the receptacle, or it may terminate at, any desired point thereon. The lower portion of this spout or tube opens into the lower portion of the receptacle, and

its upper and lower ends are closed by the respeotive slide gates D, D,- which may be adjusted to permit the insertion of water to,'or its drainage from, the receptacle. By the pro vision of this spout or tubev I am enabled to introduce hot water into the receptacle without the necessity of pouring it upon and over the dishes, a practice objected to by many housekeepers. The receptacle may be drained by tipping it slightly.

E designates the removable cover of the receptacle,which is of considerable convexity or height, and which is cut away at its central portion to form an opening of considerable size, themarginal portion of the metal around such opening being bent or flanged inwardly, as indicated at e. Closing this central opening of the cover is a raised cap-piece F,which has a marginaldepression f, arranged to receive the flange e of the cover as the latare a series ofradiating discharging or spraying arms I. Said arms where they join the tube G are shown as provided with outwardly opening valves. I. Said valves are not howoperation of the invention. I

J, J, show a second and larger tube which concentrically surrounds the tube G, and which extends to, or very near to, the bottom of the receptacle. Said tube J consists of an upper section whose upper end screws onto, or

is otherwise connected to, a-ring or cap j car-' riedby the tube G, and which closes the upper end of tube J, and a lower perforated section J which has a screw or other connection j with the section J. Said section J is closed at its upper end by an annular ring K. Atthe upper portion of the section J area series of discharging or spraying arms Lysaid arms in the form of pipes extending down between the two tubes to a point slightly above the ports is, where they terminate in open ends.

The operation of the machine as thus far described, is as follows: The dishes are arranged upon the perforated false bottom, and a suitable quantity of hot water is introduced into the receptacle through the external fill- IOC ing spout or tube. This water enters the section J of the outer tube through the perforations thereof. The piston rod and piston are now reciprocated, the latter working somewhat loosely in the tube G, so that upon the down stroke, considerable water will be forced up around and above it. Upon the up stroke, the valve G is opened and water is drawn up into the inner tube which, upon the down stroke escapes through the ports 7:. into the space between the two tubes. After a few reciprocations of the piston, this space becomes filled, or nearly filled, with water, which is then forced up into the arms L, and is discharged therefrom upon each down-stroke. Upon the up-stroke the accumulated water above the piston is discharged from the arms I, and in this manner a continual discharge upon the dishes is kept upso long as the piston is reciprocated, the discharged water draining down through the false bottom. The operation is greatly facilitated by the action of the steam from the hot water rising through such bottom the receptacle usually being placed upon a stove or other heater during the operation. The space between the two tubes being at the outset filled with air, it is obvious that as this space becomes filled with water, this air is compressed, forming at the upper portion of the space an elastic cushion, the effect or reaction of which assists in the discharge of waterfrom the arms L. The arms I and L will preferably be made of different lengths and will have their nozzles bent at different angles so that the discharge will be upon practically the entire area of the false bottom.

It will be observed that allwater entering the pump must come through the perforated section J of the outer tube, the result being that the dirt from the dishes is kept outside, and the water entering the pump is kept comparatively clean.

I find that the effect of the device is greatly increased by a rotary action of the discharge from the spraying arms, and to obtain this action, the cap piece F may be rotatedwith one hand (by, means of suitable handles or rings P) while the piston is actuated with the other hand; or, the action may be efieoted mechanically by the construction shown in the drawin gs, wherein the piston'is formed with a twist or spiral 0", which engages a corresponding bearing R in the cap of the inner tube. This arrangement will cause both tubes, the cappiece, and the discharging arms to rotate upon the reciprocation of thepiston, the bearing for the cap-piece being at its marginal engagement with the cover. The character of the twist or spiral r, is preferably such as to cause a single complete rotation to each stroke of the piston.

In Figs. 3 and 6, I have shown the piston 11' as threaded upon the shaft II? in order that it may be adjusted vertically to vary the stroke.

The outer tube may be provided at its lower end with a bearing stud S working in a step S, as seen in Fig. 1, or the inner tube may have a similar stud S working instep S as seen in Fig. 3.

In order to permit the tubes G and J, J to be removed when desired without disarranging the dishes on the false bottom, the said bottom may be provided with an upward sleeve T, which extends up and loosely around the outer tube. This sleeve will retain the dishes when the tubes are removed. Said sleeve may be extended down to the true bottom of the receptacle as shown at T in Fig. 3, the extension being perforated. Such extension will take the place of the section J. In this form the perforated false bottom has an imperforated annular central portion surrounding the inner tube which separates the chamber of the perforated section from the chamber of the outer tube.

In larger sizes of the machine it maybe advisable to provide a crib or crate Wyvhich is placed into the receptacleupon the false bottom, and intowhich thedishes are then placed. Such crib or crate will save considerable handling of the dishes, and willalso permit them to be packed in such a manner as tobe more thoroughly washed.

The washing devices can all bereadily removed from the receptacle, which can then i be utilized for other purposes.
